If you set a DataSource for the Report Parameter AvailableValues and try to configure the parameter ValueMember or DisplayMember, the corresponding editor in the Web Report Designer displays the report DataSource instead of the parameter DataSource. For that reason, the correct fields cannot be selected from the editor and must be typed manually. The linked video demonstrates the problem.

Currently, you may aggregate values from a certain scope for a particular page with the Page function PageExec. It would be great to be able to display also the carryover aggregates up to the current page. 

For example:

Page 1: Page1 Sum = 10; Total Sum at the end of the page1 = 10
Page 2: Page2 Sum = 5;   Total Sum at the end of the page2 = 15
Page 3: Page3 Sum = 13; Total Sum at the end of the page3 = 28

The issue occurs when a report contains a subreport with InstanceReportSource set as its ReportSource. If the report definition in this InstanceReportSource contains data sources, they will be serialized as DataSourceRef objects instead of using their actual type names like EntityDataSource, CsvDataSource, etc.

The issue is reproducible only in Standalone Report Designer, i.e. serializing/deserializing the report definition programmatically would work as expected.

The issue is introduced in Telerik Reporting R1 2019.

When configuring a WebServiceDataSource in the Web Report Designer in ASP.NET,  upon previewing the data there is an error '404 Not Found". The same web service was successfully resolved by the Standalone designer and in the ASP.NET Core demo.

The data source fields were visible and usable in the designer also under ASP.NET Web Report Designer.

The GroupExplorer tool window should preserve the width of its columns when changing the currently selected item on the designer surface. The current behavior is to set all column widths to their defaults when the selection changes or the selected component is being modified.

Generate and distribute packages built against .Net 5.0.

Currently .Net 5.0 RC1 and .Net 5.0 RC2 are announced. The official version has been announced on 10th of November.

In organizations like ours, it is not allowed to store the user id and password in appsettings.json. It is becoming a common practice to use AccessToken in the connection string rather than a username and password. For example, in Azure. It would be great if AccessToken could be supported out of the box in the SqlDataSource.

We use telerik reporting service in ASP.NET Core 3 on CentOS 8 server.
I just confused in spesific kanji is not show in preview and pdf.

"備考" is not shown,but "考備" is shown, reason why?(see attached xslx file)
Private Font settings will be fine(see attached reportsettings.json),because of gothic and mincho font is displayed.
If set double byte space ("備考　") is displyaed... I dont know reason why.

We install libgdiplus API in cent OS server, but not well.
hiragana is OK, but some types of Kanji is Not OK.

We already running on Windows server is not having same issue(always displayed)

We think some issue in textbox sizing algorythm in Telerik Reporing on Linux ( I used latest version 14.2.20.916)

We look forward to hearing from you.

Currently, the XLS export format is not available in .NET Core projects. Please, bring back this option.

I have a PictureBox item with a background image and no image value. When rendering in either of the Excel formats from a web application or from the Standalone designer, they throw an "Object reference not set to an instance of an object." exception. Here is the response from Fiddler:

{"message":"","exceptionMessage":"Object reference not set to an instance of an object.","exceptionType":"Telerik.Reporting.Services.Engine.DocumentRenderException","stackTrace":"   at Telerik.Reporting.Services.Engine.Document.GetDocumentInfo()\r\n   at Telerik.Reporting.Services.WebApi.ReportsControllerBase.GetDocumentInfo(String clientID, String instanceID, String documentID)\r\n   at lambda_method(Closure , Object , Object[] )\r\n   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass6_2.<GetExecutor>b__2(Object instance, Object[] methodParameters)\r\n   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ExecuteAsync(HttpControllerContext controllerContext, IDictionary`2 arguments, CancellationToken cancellationToken)\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Controllers.ApiControllerActionInvoker.<InvokeActionAsyncCore>d__1.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Controllers.ActionFilterResult.<ExecuteAsync>d__5.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Controllers.ExceptionFilterResult.<ExecuteAsync>d__6.MoveNext()"}

In my report, there is a Table with one group and PageBreak set to After for the group. If the property ColumnHeadersPrintOnEveryPage is with the default value False, in Interactive view there are three pages generated, one for each group, which is correct.

If I set ColumnHeadersPrintOnEveryPage to True, the number of pages increases to four in the Interactive view mode. There is an additional page break introduced in the last group.

After upgrading from Telerik Reporting 2020 R2 (14.1.20.618) to 2020 R3 (14.2.20.916) my reports can no longer render an image that they have always rendered before.

The images are displayed correctly in Visual Studio Report Designer Preview mode but are not displayed in HtmlPreview mode.

This will allow the SVG images to retain high quality at all zoom levels.

Currently, when using the ODBC Microsoft text driver to connect to a text file, the Query Designer in the Standalone Designer throws Object Reference Not Set To An Instance of an Object exception.

When you bind the Style.BackgroundImage.ImageData property of the PageHeader section to the value of a report parameter (a valid URL), it is not respected.

Shapes are rendered in <img> tags in Html rendering, which slows down overall rendering. In other formats like PDF, the same report runs fast.

Currently, the auth token is not yet passed from the client to the service. For that reason, it would be nice if the bearer token can be passed with the Web Report Designer API Requests.

After upgrading to 14.2.20.916, the PictureBox control is no longer loading an image via URL due to a URL limit of 260 characters. We use Google static images which can have much longer URL lengths.

Hi there,

Adding an external style sheet to a report in a report-book triggers an error when previewing the report book, "Object reference not set to an instance of an object" 

I've attached the bare minimum project to reproduce the error.

I've also tried upgrading to R3 2020

Cheers
